IMPRbVEMENT IN MlTERlNG-MACHINES.

Specification forming part of Letters Patent No. 1 88,657, dated March20, 1877; application filed January 29, I877.

To all whom it may concern:

Be it known that we, JOSIAH H. MOSHER, and JOHN PENNINGTON, of Pewamo,in the county of Ionia and State of Michigan, have invented anImprovement in Mitering-Machines, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a top view, and Fig. 2a vertical transverse section on line :0 m, Fig. l, of our improvedmitering-machine for joining picture-frames, moldings, 8m.

Similar letters of reference indicate corresponding parts.

Our invention relates to an improved mitering-machine, for use in themanufacture of pictureframes, molded frames, and for the cutting andputting together of frames on any desired angle and length.

The invention consists of a basepiece with graduated guide-rails,carrying the sliding frame-supports, with adjustable saw-guides securedthereto.

In the drawing, A represents a base piece of suitable length, whichcarries, on grooved parallel guide-rails B, the sliding supports 0, forthe frame or molding. The sliding supports 0 are set for any length ofmolding or frame along one of the guide-rails, having a graduated scale,as shown in Fig. l. The sliding supports 0 carry the adjustablesawguides D, which are set by fastening clampscrews a along guides 11for any thickness of saw, or closer together when their adjoining sidesare worn out by the saw. The sliding supports 0 have raised cornerstripsd. against which the moldings are pressed by the clampscrews E, thatturn in posts attached to the supports.

The moldings are first out at the required miter, and then brought to aperfect joint by running the saw through the joint of the moldings whilethey are firmly clamped together. The moldings are then fastened by glueand nails, and thereby two corners of the frame connected in an easy,quick, and effective manner. The mitering and jointing of frames andmoldings is thus accomplished by a simple, accurate, andreadily-operated device.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination of the sliding supports 0 G,having adjustable saw-guides D D, and frame-clamping screws E, with thebase A, provided with guide-rails B, as and for the purpose set forth.
